The species of the genus Trifolium differ by the number of pollen sacs in stamen heads. Some have only two, other four and in some species there arę two, three or four pollen sacs. The opinion of some authors (Schnarf 1931, Davis 1966) that from this point of view this genus is uniform is wrong. There is some dependence between the chromosome number (2n) and the number of pollen sacs. For two species - T. carmeli and T. desvauxii - the chromosome numbers 2n=14 were established for the first time.
